Intro
This is my Knex model 24 stick grenade. I give credit to knexxpro for the warhead, although I got the idea from TheMoonMaster's essential guide to Knex grenades.When I saw the first one, I thought I could make that look like a stick grenade's warhead. He did say it was Mykailo's grenade, so I will give him credit, too.

Pros:
looks good
VERY comfortable to hold
Realistic

Cons:
Uses one broken piece, but you don't need it to be broken

Options:
you can fill the warhead with shrapnel, but I didn't

Step 5: Igniting the Fuse

simply take the orange connector at the bottom, snap it off the middle black rod, simulating unscrewing the bottom, pull it and let go simulating pulling the twine that falls out of the hollow handle that ignites the fuse, and throw!
